Abstract
The present disclosure relates to methodologies, systems, and apparatus for controlling fluid flow within a chromatography system. The chromatography system includes a mobile phase pump configured to pump a liquid mobile phase through a column and a restrictor positioned downstream of the column and upstream of a detector. The system also includes a valve configured to operate in at least two positions. In a first position, the valve is configured to direct the output of the column to bypass the valve and reach the detector, while in the second position the valve directs the output of the column to waste.
